:DRINK MIXER.

i f Application led 'March 8,- 1922. .Serial No. 541,911.

To all whom it may concern: Be it known-that I, RAYMOND B. GIL- oHRIsT,a citizen of the United States, and a resident of Newark, in the countyof Es- 5 sex and State of New Jersey, have invented certain new anduseful improvements in Drink Mixers, of which the following is a full,clear, and exact description.

The invention relates to drink mixers. ln machines for this purpose, theliquid constituents of the drink to be mixed are usually poured into areceptacle which is generally designated a shaker,? from many diierentcontainers disposed away from the mixer. rlhe receptacle with theseconstituents'therein is brought to the mixer and placed in operativerelation thereto and is removed from the machine after each mixingoperation, to discharge its contents. This is rendered necessary,because so many different ingredients and flavors are used in makingdrinks that they are, in nearly all cases, mixed individually. lt isusually necessary to run the agitator fora considerable period toproperly blend or mix the constituents and, therefore,l itis desirablethat provision be made for retaining the receptacle and agitator.- inoperative relation to permit the dispenser to perform other dutiesduring the mixing operation. in drinkmixing, it thus becomes necessaryto frequently place the receptacle containing the constituents intocooperative relation to the agitator and/,to withdraw it from themachine to discharge its contents and cleanse the receptacle betweenmixing operations.

A desideratum in this art is to expedite and simplify the operationsnecessary to bring the receptacle and agitator into cooperativerelation, to maintain them in such relation, in starting and stopping ofthe motor and thef removal" of the receptacle. Heretofore, in machineswhereof I am' aware (excepting those exhibited in other concurr rentlypending applications), it has been necessary in their use to 'manuallymanipulate the receptacle into operative position and withdraw ittherefrom and to additionally perform some separate step. or opera- 0tion, such as lowering the motor and agitator together, or shifting theagitator and its shaft into the receptacle and relatively to themotor,or raising and locking a receptacle-support to establish andmaintain cooperative relation of the receptacle and agitator or tocontrol the operation of the machlne. Another desideratum in this art isto slmpllfy the machine by dispensing with movable connections in andfor the driving mechanism for the agitator.

One object of the present invention is to provide an improved drinkmixer in which these additional operations or steps are ydispensed withand in which manual shift of the receptacle is utilized to completelycontrol t he operation of the machine and t'o secure 1t and the agitatorin cooperative relation. By dispensing with the necessity ,of theseadditional steps or operations, the time of the dispenser in performingthem is saved and the service is improved.

Another object of `the invention is to provide a machine of this typevin which movf able connections in and for the driving melianism for theagitator/are dispensed W1v Another Object of the invention is to provide a machine which is simple in construction, which may be easily andreadily operated and which is eiicient in operation.

Other objects of the invention`- will more fullyv appear fromhthefollowing Idescripion.

The invention consists in the several novel features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

ln the drawings: Fig. 1 is a vertical section of a machine embodying theinvention parts being shown in elevation. is a section on line 2-2^ofFig. 1l. Fig 3 is wa detaliof the hook-connection between the)receptacle and the guide. i

rllhe invention is exemplied in a machine comprising an electric motorl() of usual construction, to the rotor of which is secured a pendentshaft 11 with an agitator 12 fixed to its lower end; a hollow supportingstand.

ard comprising a lower portion 13 fixed to a bottom-member 14; which issecured to a base d5 by a -screw 16, and an upper member 17 suitablysecured in the member 13; and a bracket 18 suitably secured to the upperend of member 17, to which the motor 10 is suitably secured, as at 19.The electrical connections for supplying energy to the mo- Fig. 2

tor 1() comprise a conductor-cord 20 leading through a handle 2l andcomprising con- 24 and 25 being included in the conductor 23 to controlthe operation of the motoxr. The casing of the motor 10 is lixedlysecured to the support at 19 and the agitator 12 is maintained insubstantially relatively fixed vertical relation to the motor.

A receptacle 26 having an open top, a closed bottom 27 and an upperdownwardly extending flange 29, is adapted to contain the constituentsof the drink to be mixed and to be placed into cooperative relation to"the agitator from beneath the latter, which` is supported sufficientlyabove the base115 to permit the insertion 4and .withdrawal of thereceptacle. l

The invention contemplates placement of' the receptacle into andout ofoperative relation to the agitator, locking and unlocking the receptacleand control of Athe motor by manipulation of the receptacle itself, sothat shift of the ymotor or the agitator are not necessary to bring theagitator into working position in the receptacle. For this purpose, astationary vertically extending receptacle-guide is provided for theback of the receptacle and comprises a lower inclined or upwardly andbackwardly sloping member or portion 3() and a vertical upper` portion31, The guide has its front face curved or arcuate in substantialconformity with the outer periphery of the' receptacle so that when thelatter is pressed backwardly against the guide, the receptacle will beguided against lateral movement and int-o its operative position withoutdanger of striking the agitator 12.

The receptacle is adapted to be removably secured in its operativeposition by the flange 2.9 which constitutes an annular hook adapted toextend around the arcuate upper end of the stationary guide member 31. Aguard member 33, which is secured to standard member 17 by screws 33',extends over the upper rim of the receptacle and downwardly into it soas to form a stop for limiting the upward movement of the receptacle andalso for limiting the forward movement of the upper portion of thereceptacle, to

prevent it from striking the agitator. By

suspending the rear portion of the receptacle from the upper end of .theguide, the

Weight of the front portipn of the receptacle and the material thereinwill tend to hold the'receptacle against guide member 31. The

stationary receptacle guide is secured to the standard by lugs 32.

For the purpose of ling the operation of the motor by manipulation -ofthe receptacle, a switch-lever 34 has its lower end 35 formed topivotallyit in the lower` end -`of the standard-member 13 and on theplate 14, is extended through a slot 36 in front of thesupporting-standard andi tol cause the automatically control-l distanceto operate the motor-switch. Lever.

34 is also formed vwith a cam 39 in the hol-k low standard, to shift andcontrol a plunger 40 which is slidably held in the hollowstandard andcarries'a switch-pin 41 at its upper end which is adapted tobridge thegap between the normally separated switch-member-S24 and 25 and closethe circuit. for the operation of motor f10. Switch-members 24 and25-aresecured to a block 42 of insulating material. Plunger 40 may7 be formedof insulating material, (such as wood, and is normally presseddownwardlyby a spring 43 interposed between a shoulder on the plug and aplate ofinsulating material 44 suitably held in the upper end lof thestandard-member 17. A' wear-plate 45 is secured to the lower end ofplunger 40.

The operation of the machine will be as follows: Assuming the parts tobe in ndrmal position shown in Fig. 1, theoperator will place receptacle26,-containing the constituents of the drink to be mixed, againstinclined guide-member 30 and under ,the agi- .tator 12, as shown bydotted linesfin Fig.

1, press it rearwardly with suilcientforce guide to llaterally controlits vertical movement, and then lift it. In this manipulation., thereceptacle will slide on the front-face of the receptacle-guide. Afterthe receptacle leaves the inclinedguide-member 30, it will bear againstth'e vertical guide;

member 31 and be raised until its upper margin into the holder-member33` When the receptacle strikes member 33, the hook flange 29 will slipbackwardly above the upper end of guide member 30. The operator willthen release'` the receptacle or exert a downward pressure on it tocause the hook-flange and the guide to positively interlock and secureth'e receptacle -in its operative position. In 'its upward movement,-

the receptacle will engage the cam 38 and rock lever 34 about its lowerend so that cam 39 will raise plunger 40,l cause the pin 41 to bridgeswitch-members 24, 25 and close the circuit for the operation of themotor 10 and cause it to drive the agitatof'. Thisoccurs, preferablybefore the receptacle reaches its operative position. .The hookconnection between 4the receptacle and the guide positively holds thereceptacle, so that it will not be displaced b y the forward pressure ofswitch-lever 34, which is under the influence of spring 43, which tendsto hold the switchthe operator will lower the receptacle and r press itbackwardly,so that it will be held in the stationary guideway until ithas been lowered to clear the agitator when it may be withdrawnforwa-rdlly. During the lowering of the receptacle, the switch-lever 34will pass into its normaliposition to release plunger and cause it tobreak the circuit and stop the motor. This occurs preferably after thevessel has been lowered, to bring the liquid therein below the agitator,so the latter will run for a` period to discharge the adherent liquid bycentrifugal force before the agitator leaves the upper end of thereceptacl'e.

The invention exemplifies a machine of the character described, in whichthe receptacle is manually placed and/locked in its ope-ra.- tiveposition; in which such placement controls the motor; which is simple inconstruction and avoids the necessity of a shiftable agitator.

The invention is not to be understood as restricted tothe details setforth, since these may be modified within the scope of the appendedclaims, without`departing from the spirit and scope of the invention.
